Aktuelle Bremssysteme, beispielsweise in der Kraftfahrzeugtechnik, welche auf dem Prinzip der Hydraulik basieren, haben Reaktionszeiten von etwa Hundert Millisekunden. Der vorliegende Aktuator besitzt eine Reaktionszeit von wenigen Millisekunden. Diese Tatsache wird die Leistungsfähigkeit von Bremssystemen entscheidend beeinflussen.current Brake systems, for example in automotive engineering, which Based on the principle of hydraulics, have reaction times of about a hundred milliseconds. The present actuator has a Response time of a few milliseconds. This fact becomes the Decisively influence the performance of brake systems.
Das vorliegende Bremssystem verfügt darüber hinaus über die Fähigkeit Verschleiß auszugleichen. Der selbsttätige Nachstellmechanismus gewährleistet einen konstanten Spalt zwischen Bremsbelag und Bremsscheibe und damit ein gut kontrollierbares Bremsverhalten. Jeder Bremsbelag kann über ein solches Ausgleichssystem verfügen.The present braking system also has over the ability to compensate for wear. The automatic Adjustment mechanism ensures a constant gap between brake pad and brake disc and thus a good controllable Braking. Each brake pad can have one Balance system.

Eine herausragende Charakteristik der vorliegenden Erfindung ist der Nachstellmechanismus zum Ausgleich von Verschleiß. Dieser Mechanismus ist erforderlich um eine hohe Effizienz und Zuverlässigkeit des Bremssystems zu erzielen. Der Nachstellmechanismus ist erforderlich, um eine gleichmäßige Spaltbreite zwischen Bremsbelägen und Gehäuse zu gewährleisten; bei der Spaltbreite handelt es sich um einen entscheidenden Parameter für die Funktion des Bremssystems, da hierdurch die nötige Ausdehnung des Aktuators vorgegeben wird. Ein vergrößerter Spalt kann das Bremsmoment reduzieren.A outstanding characteristic of the present invention is the Adjustment mechanism to compensate for wear. This Mechanism is required for high efficiency and reliability to achieve the braking system. The adjustment mechanism is required by a uniform gap width between brake pads and to ensure housing; at the gap width it is a crucial parameter for the Function of the brake system, as this causes the necessary expansion of the actuator is specified. An enlarged one Gap can reduce the braking torque.
Eine vergrößerte Spaltbreite kann sich durch Verschleiß ergeben. Ein Nachstellmechanismus kann diese Effekte kompensieren und eine elektrische Nachregelung ersetzen. Außerdem sind einer elektrischen Nachregelung physikalische Grenzen gesetzt.A increased gap width can result from wear. An adjustment mechanism can compensate for these effects and a Replace electrical readjustment. There are also an electric Readjustment set physical limits.
